Getting started

Install powermise, let it set up mise, and take a first look around.

powermise is an unofficial companion to mise — it isn’t made by the mise team. It runs on macOS, Windows, and Linux.

1. Install powermise

The quickest way is the install script, which downloads the latest release, checks it against the release’s checksums, and installs it:

# macOS and Linux
curl -fsSL https://powermise.pages.dev/install.sh | sh

# Windows (PowerShell)
irm https://powermise.pages.dev/install.ps1 | iex

On macOS it puts powermise.app in Applications. On Linux it installs the .deb or .rpm through your package manager (which asks for your password), or the AppImage in ~/.local/bin where neither fits. On Windows it installs for your account only, with no administrator prompt.

Or download an installer from the latest release:

System	File
macOS (Apple Silicon and Intel)	`powermise-macos-universal.dmg`
Windows	`powermise-windows-x64-setup.exe` (or the `.msi`)
Linux x64	`powermise-linux-x86_64.AppImage`, `-amd64.deb`, or `-x86_64.rpm`
Linux ARM	`powermise-linux-aarch64.AppImage`, `-arm64.deb`, or `-aarch64.rpm`

Opening it the first time

powermise isn’t code-signed yet: Apple and Microsoft can’t vouch for who made it, so your system asks before opening it the first time. That’s one extra step, once. The install script skips it on macOS, and on Linux there’s nothing to approve.

macOS. Opening a downloaded copy shows “powermise” Not Opened (or Apple could not verify…). Click Done, then either:

open System Settings › Privacy & Security, scroll to Security, click Open Anyway next to “powermise” was blocked, and confirm with your password; or
run this in Terminal, then open powermise as usual:
Terminal window
```
xattr -dr com.apple.quarantine /Applications/powermise.app
```

Windows. If Windows protected your PC appears, click More info, then Run anyway. The install script doesn’t trigger this.

Linux. The .deb and .rpm install like any local package — nothing to approve (the install script uses them). An AppImage needs two things first:

make it executable — chmod +x powermise-linux-*.AppImage, or tick Allow executing file as program in its Properties;
FUSE 2 — sudo apt install libfuse2 (libfuse2t64 on Ubuntu 24.04 and later), sudo dnf install fuse-libs, or sudo pacman -S fuse2.

2. mise

powermise runs mise for everything it does. If you don’t have it, the Welcome screen installs it for you — mise’s own installer on macOS and Linux, winget or Scoop on Windows — and shows the one line that turns it on in your terminal. powermise works with mise 2026.7.18 or newer, and is designed around 2026.10 or newer, the version a fresh install gets.

3. Look around

After Welcome, powermise opens on Home, with a checklist that ticks itself off:

Turn mise on in your terminal — Home shows the one line to add.
Open Discover, pick a tool, and click Install. powermise shows the exact mise use -g … command first, then mise’s own output while it runs.
Add a project folder to see the tools and tasks it uses.
If another version manager installed some versions, Bring over versions you already have opens Import. It also brings over Homebrew packages and command-line tools you installed another way, with a dry run before anything changes.

My Tools shows what’s installed and what has an update; Health lists anything that needs attention, with the fix.

The app tour walks through each screen.

Try it without installing

The live demo on the homepage runs the real app in your browser with pretend data. Nothing it does touches your computer.

Build from source

You’ll need Bun and Rust. On macOS, also the Xcode command line tools (xcode-select --install); on Linux, the Tauri system dependencies.

git clone https://github.com/frankievalentine/powermise.git
cd powermise
bun install
bun run desktop:build

The finished app is in apps/desktop/src-tauri/target/release/bundle/. To run it straight from the source instead:

bun run desktop:dev
